Lecture Scope (Week 2 – Safety)

  • Aviation‐safety overview

  • Accident vs. proactive safety philosophies

  • ICAO management frameworks (Annex 13 vs. Annex 19)

  • Safety-investigation systems and authorities

  • Australian safety agencies: CASA, ATSB, Airservices, DITRDCA

  • Strategic and audit programmes: USOAP, IOSA, NASP, etc.

Aviation-Safety Foundations

  • Definition (ICAO Annex 19):

    • “A state in which the possibility of harm to persons or property is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and safety-risk management.”

  • Key characteristics

    • Focus on acceptable (not zero) risk in a complex, high-risk industry

    • Continuous, dynamic and system-wide activity (rules, tech, training, oversight)

  • Two complementary views of safety

    1. Human-Factors View

    • Human error = primary causal agent ⇒ study behaviours, improve training, design & procedures

    1. Safety-Management View

    • Error = symptom of deeper system weaknesses ⇒ fix organisational, cultural & procedural roots

Annex 13 vs. Annex 19 (Reactive ↔ Proactive)

  • Annex 13 – Aircraft Accident & Incident Investigation

    • International standards for evidence collection, stakeholder involvement, report writing

    • Purpose = Prevention of recurrence, not blame ⇒ fosters a “Just Culture”

    • Reactive: only triggered after an occurrence

  • Annex 19 – Safety Management

    • Mandates State Safety Programme (SSP) & organisational Safety Management System (SMS)

    • Integrates lessons from Annex 13 into day-to-day risk control

    • Proactive: anticipates & mitigates hazards before accidents

ICAO Global Aviation Safety Plan (GASP 2023–2025)

  • Vision =0 fatalities in commercial ops by 2030+

  • Aligns with UN SDGs (safe, resilient, sustainable aviation)

  • Six global goals

    1. Reduce operational‐safety risks (focus on data-driven prevention)

    2. Strengthen States’ safety oversight

    3. Implement effective SSP

    4. Enhance regional collaboration (RASGs, RSOOs)

    5. Expand industry programmes & data sharing

    6. Improve infrastructure (runways, ANS, ATC tech)

  • Global High-Risk Categories (G-HRC)

    • Controlled Flight Into Terrain (CFIT)

    • Loss of Control In-Flight (LOC-I)

    • Mid-Air Collision (MAC)

    • Runway Excursion (RE)

    • Runway Incursion (RI)

  • Implementation tools

    • National Aviation Safety Plans (NASP)

    • Regional Aviation Safety Plans (RASP)

    • Global Aviation Safety Roadmap (Doc 10161 → how to do it)

    • Three-year review cycle & continuous monitoring

Safety-Investigation Systems

  • Each ICAO State must create an Accident Investigation Authority (AIA) independent of regulator/service provider (e.g., NTSB, ATSB)

  • Principles

    • Independence avoids political/commercial influence

    • State of Occurrence leads; States of Registry, Operator & Manufacturer participate

    • Evidence: physical wreckage, FDR/CVR data, witness testimony

  • Four pillars of SMS (ICAO)

    1. Safety Policy & objectives (leadership, accountability, ERP)

    2. Safety-Risk Management (hazard ID, risk assessment, mitigation)

    3. Safety Assurance (monitoring, audits, continuous improvement)

    4. Safety Promotion (training, comms, safety culture)

  • Investigation challenges

    • Multinational politics & coordination

    • Balancing transparency with privacy (e.g., releasing CVR audio)

    • Psychological toll on investigators

    • Use of CICTT occurrence categories for global trend analysis

  • Why investigate?

    • Identify root causes, prevent recurrences, save money, improve morale & reputation

Global Safety-Audit & Oversight Programmes

  • USOAP (CMA) – ICAO: audits 8 critical elements of State oversight; scores published for transparency

  • IASA – FAA: Category 1 (meets SARPs) vs. Category 2 (doesn’t) for U.S. market access

  • SAFA / EU Blacklist – EASA: ramp inspections & bans unsafe foreign airlines

  • IOSA – IATA: bi-annual airline audit prerequisite for IATA membership

  • Other systems

    • USAP ext{-}CMA (aviation security – Annex 17)

    • ICAO SSP requirements (State level, proactive)

Australian Aviation-Safety Architecture

  • Civil Aviation Safety Authority (CASA)

    • Regulates safety, licenses personnel, registers aircraft, certifies aerodromes

  • Australian Transport Safety Bureau (ATSB)

    • Independent investigator; publishes safety recommendations; runs confidential REPCON scheme

  • Airservices Australia

    • Government-owned; provides ATC, ARFF, navigation & comms systems

  • Department of Infrastructure, Transport, Regional Development, Communications & the Arts (DITRDCA)

    • Develops policy & legislation; coordinates with ICAO; oversees national SSP

  • National programmes

    • Australia holds FAA IASA Category 1, participates in USOAP (latest audit 2023/24 – effective oversight)

    • NASP 2024–2027 aligns with GASP goals & local risks

    • REPCON fosters non-punitive reporting culture

  • Legal foundations: Civil Aviation Act, Airspace Act, CARs/CASRs

Risk-Management Foundations

  • Risk formula \text{Risk}=\text{Severity}\times\text{Likelihood}

  • Seven-step assessment process

    1. Identify hazards (observe, review data, consult staff)

    2. Identify associated risks & contributing factors (record in register)

    3. Evaluate (severity/likelihood matrix ⇒ prioritise)

    4. Mitigate (apply Hierarchy of Controls + ALARP/SFAIRP)

    5. Record & implement actions (assign owners, deadlines)

    6. Monitor effectiveness (feedback, KPIs)

    7. Review & update (at least annually or after change)

  • Categories of acceptability (graph)

    • Unacceptable → Tolerable (with ALARP) → Broadly acceptable

  • Bow-Tie model

    • Centre: Top Event (e.g., “car skids on wet road” / “aircraft CFIT”)

    • Left: Threats + preventive controls

    • Right: Consequences + mitigative controls

  • Hierarchy of Controls (most → least effective)

    1. Elimination

    2. Substitution

    3. Engineering controls

    4. Administrative controls

    5. PPE

Safety Management Systems – What Maturity Delivers

  • Embeds the four pillars to:

    • Reinforce critical procedures (deicing, W&B, etc.)

    • Drive accountability through audits & data analytics

    • Support decision-making under stress (tools, SOPs)

    • Enable a Just Culture for continuous learning

  • Key reminder: “Regulation provides the framework; daily frontline risk management keeps aviation safe.”

Human Factors & Non-Technical Skills (NTS)

  • Technical skills = hard, task-based competencies (tested via exams, sims)

  • NTS = communication, leadership, situational awareness, decision-making (assessed via NOTECHS)

  • Pilot HF training evolution

    1. CRM – classroom theory (teamwork, leadership)

    2. LOFT – simulator scenarios using CRM skills in realistic contexts

    3. TEM – threat & error management tailored to actual LOSA data

  • NASA 1979 workshop seeded global CRM mandate; now integral to annual pilot training (+ fatigue, stress modules)

Investigator Training Pathway

  • Three formal phases

    1. Basic classroom (laws, ethics, Annex 13, safety at site)

    2. On-the-job (shadowing, evidence preservation, interviewing)

    3. Advanced course (CVR/FDR reading, fire/origin analysis, report writing)

  • ATSB pathway example

    • Recruits often ex-pilots/engineers → internal courses → supervised field work → external programmes (e.g., Cranfield MSc) → CPD via ISASI

Case Studies & Lessons

Weight & Balance Fundamentals

  • Weight = total aircraft mass (fuel, pax, bags, cargo)

  • Balance = distribution relative to CG limits (forward CG = difficult rotation; aft CG = pitch instability)

Air Midwest Flight 5481 (USA, 08 Jan 2003)

  • Factors

    • Actual weight \approx150\,\text{kg} heavier; CG aft of limit (outdated pax/bag averages)

    • Elevator-cable mis-rigging restricted pitch control

  • Outcome: Stall after take-off; 21 fatalities

  • Aftermath

    • FAA & industry updated standard-weight tables (avg pax 88\,\text{kg} vs. historical 80\,\text{kg})

    • Highlighted Goal 1 & 2 gaps in GASP → triggered SEIs on W&B and maintenance oversight

Phenom 300 Crash (Provo, Utah, 02 Jan 2023)

  • Visible freezing drizzle; pilot skipped de-icing, de-activated Wing-Stab anti-ice

  • Stall seconds after lift-off; 1 fatality, 3 injuries

  • Demonstrates direct link between procedural non-compliance & aerodynamic failure; underscores SMS role in reinforcing SOPs/Just Culture

Strategic, Voluntary & Industry-Led Safety Systems

  • ICAO GASP / RASG / ADREP = global‐strategic & data-sharing backbone

  • Europe: ECCAIRS harmonises incident data; ITSA coordinates best-practice investigation resources

  • Industry programmes

    • IOSA (global airline audit)

    • Flight Safety Foundation (toolkits, research)

    • CAST / ASIAS (U.S. collaborative data-driven safety)

    • Confidential reporting: ASRS (USA), REPCON (AUS)

  • Benefits: performance-based, cooperative safety culture; move “beyond compliance”.

Infographics for Aviation Professionals

  • Visual, dual-coded communication: converts dense safety data (e.g., HFACS, risk models) into quick-grasp insights

  • Enhances synthesis, critical thinking & professional briefings

  • Widely used in SMS docs, ICAO/eASA summaries, FRMS reports

  • Canvas task: design a PDF infographic (rubric provided) using Annex references

Key Takeaways

  • Safety = proactive, system-wide, data-driven management of acceptable risk.

  • Annex 13 investigations feed Annex 19 SMS/SSP loops; both are essential.

  • GASP provides strategy; Roadmap, NASP & RASP operationalise it; continuous monitoring closes the loop.

  • Strong national framework (CASA/ATSB/Airservices/DITRDCA) + mature SMS on the frontline ⇒ safer skies.

  • Human factors, NTS, and robust risk-assessment tools (Bow-Tie, Hierarchy, Matrix) turn regulations into everyday safety behaviours.
